Paleolatitude.org can do that, right down to the movements of small tectonic and ‘lost continents’ now called Greater Adria, the Tethys Himalayas or Argoland, which we know as folded rocks in the mountain ranges of the Mediterranean, the Himalayas, and Indonesia.

Convergent Evolution Cheat Sheet Now 120 Million Years Old
One tenet of natural selection is a random walk of genes but nature may be more predictable than rolls of dice suggest. A new study of the mimicry of several distantly-related South American rainforest butterfly and moth species with similar wing color patterns that may warn away predators (it's not a costumed bluff, the moths and butterflies are actually toxic to birds) found that they reused the same two genes - ivory and optix - to evolve near identical color patterns.
